RHEL NAS stuff

multipath -l 

That shows me the 2 Disk

pvs 

Show the Volumes.

Adding a new Disk (Assume you have already created the new disk volume)

iscsiadm -m session --rescan

This scans to see if there are new iscsi devices

multipath -r

This Would then show up

Typicallty appearing as

/dev/mapper/mpathe

We can then create a VG etc on this device

We then need to carry out the mapping on Both nodes - so we can have auto failover.

Power off

Use the GUI and on the System Enclosure Controller right-click, and choose Power-Off, after this power can be taken off the other units (manually) as there is no physical power switch.
